pespin has submitted a patch for osmo-trx that appears to completely fix the osmo-bts-trx clock skew instability problem! Please merge it if possible :)
The issue is still there, however error rate dropped dramatically after that patch. See for instance: https://jenkins.osmocom.org/jenkins/view/osmo-gsm-tester/job/osmo-gsm-tester...
To clarify the term "dramatically": failure rate is now about three out of 50 tester runs, i.e. three out of 100 osmo-bts-trx tests. Lately it had been failing every second test, so the improvement is huge, from 50% down to 3%.
Kudos to pespin for finding that issue. Hopefully we can also get rid of the remaining odd failure.
Interesting that it doesn't happen every time, nor on everyone else's equipment. Maybe CPU speed or faster I/O makes it less likely to happen.
